This happens with all different apps and occasionally on the home screen. For the record I have an iPhone 4 on 5.0, not currently jailbroken, and I don't know if this may be a problem with iOS 5 or the hardware. I got my phone in October of last year so yeah, it's kinda old. Anyone else have this problem?
